PHP is a very popular open source server-side scripting language. Most of the websites you see on the World Wide Web are developed using PHP. However, you probably noticed strangely that a small number of people swear to stay away from PHP. But it is even more strange or shocking to say that they don't use php because of some proven language shortcomings. They decided not to use php because of misunderstanding.
Yes, those you read are misunderstandings.
Let's see the misunderstandings are:
1. PHP is an object-oriented language, but object-oriented is not thorough
This is completely wrong. All programmers who think that php is not completely object-oriented, especially Java programmers, need basic training for PHP; they will find a large number of object-oriented features in PHP. For example: interfaces, methods, abstract classes, etc. I agree that earlier PHP versions did not support too many object-oriented features, but PHP5 already has strong object-oriented support. Moreover, you must not have imagined that encoding will become so simple in PHP, because of the combination of PHP and object-oriented.
So, eliminate this misunderstanding.
Not able to implement specific functions
I'm very clear that this statement is vague, but I can't come up with any better statement. This is a very vague misunderstanding, and developers believe that PHP cannot help them implement features such as memory access or that some major PHP distributions do not provide support. But the truth is that PHP is an extensible language, so what you need to do is encode it in C or C++ and then create the corresponding extension.
Actually, you don't need to create extensions yourself at all, because there are already hundreds of extensions available here. The only thing you need to do is look for them.
It's unsafe
Another misunderstanding of PHP by developers is that PHP websites and applications are not safe. But why would you want it to be safe by default, and why not write safe code? I know there has been a lot of unsafe PHP code here because the initial learning curve was simple and easy to get started. So, as a developer, you need to make it as safe as possible.
.Net can help you be safe by default, and PHP does lack a lot by comparison. But if you are a trained programmer, then you don't actually have the security help by default. Include is usually safe, but you need to be careful. If their paths are generated dynamically, a thorough understanding of the directives can help you make your code safer.
4. It cannot be adapted to large applications
Large and complex applications need to be built on their own reliable and high-performance languages, which PHP does not have to a certain extent. But if the application architecture you design and develop is stable, why do you have questions about its performance and scalability?
In fact, some top websites, such as Facebook, Wikipedia, Yahoo, etc., are built on PHP, and as we thought, these giant websites work very well.
5. PHP can only be used for website development
This is also a misunderstanding, although it seems a bit logical, as PHP is the most common language in website development. But there are also things called command line interfaces that ensure that your PHP application can run outside of the web server.
You may not believe it, but even applications that depend heavily on CPU capabilities can be developed in PHP and run using the PHP CLI.
More importantly, if you want to develop desktop applications using PHP, don't worry, you can do this with Windows specific extensions.
6. The development process is slow
This is a misunderstanding that has been widely circulated. I don't know where it originated? This rumor may come from a time when the php code was messy and the code was filled with Mysql statements (they used this as a counterexample, but in fact we don't use it like this). The question is why the development process is slower like this? When a large number of php frameworks appear, the development process can be greatly accelerated. Needless to say, you can develop a big program in a short time, no matter how complex it is. So, you are not slow to develop with php at all, especially when you use php framework.
7. Professional developers do not use PHP
PHP is for beginners, and it is designed for those who are not serious about development. These statements are related to the use of PHP. It's just a misunderstanding, and it doesn't make any sense to agree with it. There are so many network applications here, including some large ones, built using PHP. You can imagine how incorrect these statements are.
8. Performance issues
This is a tough question. This is not a misunderstanding. Like a coin, this problem is also two-sided. In fact, it is full of garbage code, implicit conversions, inapplicable modules, lack of operator overloading, etc. can all affect the performance of a php application. But this depends on whether you have enough ability to use this language well and write it to apply it stably and quickly.
Performance is determined by the architecture you design and the code you write!
9. Cheap but not good
This seems to be logically strong, but using it on PHP is a complete misunderstanding! In fact, the biggest advantage of php is its free and open source, which means that most developers who provide application development services must be proficient in it. Although free open source brings some problems, it also provides cost advantages for customers who use their services. Compared with commercial development languages, php's development cost is lower, but this does not mean that its quality is questionable. Working with the right developers can get higher performance php applications.
10. PHP is exaggerated
Is this really the case? You just talk nonsense. I don't think so, and many developers don't think so either.
Conclusion
This is not the endorsement of all php lies. As the php language continues to develop and become stronger, misunderstandings will also grow. But please don't be fooled by them. Read more, ask more, do your own things, and then you will know if it is true.
